RHEL 7 : Red Hat Enterprise Linux OpenStack Platform Installer update (Important) (RHSA-2015:0791)

critical Nessus Plugin ID 210222

Synopsis

The remote Red Hat host is missing a security update.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2015:0791 advisory.

Red Hat Enterprise OpenStack Platform Installer is a deployment management tool. It provides a web user interface for managing the installation and configuration of remote systems. Deployment of changes is performed using Puppet. Additionally, Dynamic Host Configuration Protocol (DHCP), Domain Name System (DNS), Preboot Execution Environment (PXE), and Trivial File Transfer Protocol (TFTP) services can be provided. Controlling these services also enables provisioning of physical systems that do not yet have an operating system installed.

It was discovered that the puppet manifests, as provided with the openstack-puppet-modules package, would configure the pcsd daemon with a known default password. If this password was not changed and an attacker was able to gain access to pcsd, they could potentially run shell commands as root. (CVE-2015-1842)

Note: This flaw only affects Red Hat Enterprise Linux OpenStack Platform installations deployed using the HA feature set.

For additional information on addressing this flaw see:

This issue was discovered by Alessandro Vozza of Red Hat.

In addition to the above issue, this update also addresses multiple bugs which are documented in the Red Hat Enterprise Linux OpenStack Platform Technical Notes, linked to in the References section.

All Red Hat Enterprise Linux OpenStack Platform Installer users are advised to upgrade to these updated packages, which correct these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
